46e2eadad2 Do not set properties in bionic_systrace
Currently, if the debug.atrace.tags.enableflags property is not found,
it is set to a safe value such that a pointer to this property can be
stored for later access.  This may result in selinux denials because not
all processes write permissions for this property or permission to
connect to the property write socket at all.

Change I6d953c0c281fd72ad3eba8a479fd258023579b5b writes this property to
a safe value upon boot, which greatly decreases the cases in which this
property will not be accessible and removes the need to write it here.
This commit removes this write.

40360b379c Remove bogus transitive includes.
<signal.h> shouldn't get you the contents of <errno.h>, and <fcntl.h>
shouldn't get you the contents of <unistd.h>.

a406ee6d5f Added a bionic systrace class and tracing to pthread_mutex.cpp.
bionic_systrace.h contains an implementation of tracing that
can be used with systrace.py and its associated viewer.  pthread_mutex
now uses this tracing to track pthread_mutex contention, which can be
enabled by using the "bionic" command line option to systrace.
